Struct AdaptiveParking 

pub struct AdaptiveParking { /* private fields */ }

Mode-gated reposition: dispatches to an inner strategy chosen by the current TrafficMode.

Closes the playground-reported “chaotic repositioning” complaint: the single-strategy defaults either lock cars to the lobby (ReturnToLobby) or shuttle them toward the hottest stop (PredictiveParking) regardless of traffic shape. Adaptive picks per mode:

Mode	Inner
UpPeak	ReturnToLobby
InterFloor	PredictiveParking
DownPeak	PredictiveParking (today)
Idle	no-op (stay put)

The DownPeak row uses PredictiveParking for now — it’ll become a dedicated upper-floor-biased variant once TrafficDetector emits DownPeak (needs the destination-log that today’s ArrivalLog doesn’t carry). Falls back to a PredictiveParking-like default if the detector is missing from World (e.g. hand-built tests bypassing Simulation).

Implementations

impl AdaptiveParking

pub const fn new() -> Self

Create with defaults: ReturnToLobby::new() (home = stop 0) and PredictiveParking::new() (default rolling window).

pub const fn with_home(self, index: usize) -> Self

Override the home stop used during UpPeak. Same semantics as ReturnToLobby::with_home.

pub const fn with_window_ticks(self, window_ticks: u64) -> Self

Override the window used for InterFloor / DownPeak predictive parking. Same semantics as PredictiveParking::with_window_ticks.

Panics

Panics on window_ticks = 0, matching PredictiveParking.

Trait Implementations

impl Default for AdaptiveParking

fn default() -> Self

Returns the “default value” for a type.

impl RepositionStrategy for AdaptiveParking

fn reposition( &mut self, idle_elevators: &[(EntityId, f64)], stop_positions: &[(EntityId, f64)], group: &ElevatorGroup, world: &World, out: &mut Vec<(EntityId, EntityId)>, )

Decide where to reposition idle elevators.
